General Motors Train of Tomorrow

This a brochure from Frigidaire via General Motors selling you both a new kitchen and the train of tomorrow. Best I can figure out is that the train had yet to be built, this brochure is more a promise that it would be built. That puts the date on this mini-brochure probably 1945 or 1946. See all 4 pages after the jump.

This, and everything else you need to know about the Train of Tomorrow, is from Silver Rails:
After the war, General Motors ordered the four-car demonstrator set from Pullman. The all-dome train was delivered in May 1947 and toured the country as the GM "Train of Tomorrow". The consist went on exhibition tours totalling 65,000 miles. After the tour ended in 1950, Union Pacfic purchased the equipment for it's contribution to pool service in the Seattle-Portland run.
